Even in this country there are twenty great effects which, though they have, of course, suffered record, are still secure from general praise; for instance, that awful trench which opens under your feet, as it were, up north and beyond Plynlimmon. It is a valley as unexpected and as incredible in its steepness and complete isolation as any one may see in the drawings of the romantic generation of English water-colour, yet perhaps no one has drawn it; there is certainly no familiar picture of it anywhere. When one comes to think of it, the reason of such exceptions to fame as are these is usually that such and such an unknown but great sight lies off the few general roads of travel. It is a vulgar reason, but the true one. Unless men go to a mountain to climb because it is difficult to climb, or unless it often appears before them along one of their main journeys, it will remain quiet. Among such masses is the Canigou. Here is a mountain which may be compared to Etna. It is lower, indeed, in the proportion of nine to eleven; but when great isolated heights of this sort are in question, such a difference hardly counts. It can be seen, as Etna can, from the sea, though it stands a good deal more inland; it dominates, as Etna does, a very famous plain, but modern travel does nothing to bring it into the general consciousness of the world. If Spain were wealthy, or if the Spanish harbours naturally led to any place which all the rich desired to visit, the name of the Canigou would begin to grow. Where the railway skirts the sea from Narbonne to Barcelona, it is your permanent companion for a good hour in the express, and for any time you like in the ordinary trains. During at least three months in the year, its isolation is peculiarly relieved and marked by the snow, which lies above an even line all along its vast bulk. It is also one of those mountains in which one can recognise the curious regularity of the "belts" which text-books talk of. There are great forests at the base of it, just above the hot Mediterranean plain; the beech comes higher than the olive, the pines last of all; after them the pastures and the rocks. In the end of February a man climbs up from a spring that is as southern as Africa to a winter that is as northern as the highlands of Scotland, and all the while he feels that he is climbing nothing confused or vague, but one individual peak which is the genius of the whole countryside. This countryside is the Roussillon, a lordship as united as the Cerdagne; it speaks one language, shows one type of face, and is approached by but a small group of roads, and each road passes through a mountain gap. For centuries it went with Barcelona. It needed the Revolution to make it French, and it is full of Spanish memories to this day.
